Build log

------- Comment #2 From SpanKY 2008-10-23 05:44:52 0000 ------- 
since the ppc64 toolchain sucks, this probably needs to be worked around by
appending the toc flags mentioned in the log in the ebuild

updated ebuild

Confirmed. Same problem here.
Changed the ebuild to include the -mminimal-toc flag. Had to add a src_unpack
section since the qt build uses the flags from qmake. This works for me on
ppc64. The -fno-optimize-sibling-calls flag did not work, however.

thanks, ive added that to cvs for now ...

------- Comment #5 From SpanKY 2008-11-03 05:53:49 0000 ------- 
also had to commit this:

------- Comment #6 From Brent Baude 2009-04-15 14:31:00 0000 ------- 
ppc64 just upgrades to gcc-4.3.2-rX which should begin to resolve these TOC
issues.  

@vapier - how do you want to proceed on this?

------- Comment #7 From SpanKY 2009-04-18 17:25:57 0000 ------- 
could you fill in the lower details ?  last i looked at how the ppc64/TOC stuff
worked, it seems like it was broken by design and there wasnt really anything
we could do about it other than me whine like a little ho.

------- Comment #8 From Tom Gall 2009-07-05 20:09:24 0000 ------- 
I don't like to do this, but I am not able to recreate this bug.

I'm on gcc 4.3.3-r2. 

What's changed between gcc 4.1.2 and gcc 4.3.*?  I'm not the guy to ask. I'd
recommend talking to the ppc toolchain folks, bergner or bje. I thought they
had done some things to be a bit more intelligent about the TOC but that could
be complete BS. 

Anyway, I'm going to mark this works for me. 

1) upgrade your gcc if you haven't already gotten to gcc 4.3.* 

2) make sure when you do the upgrade you follow the ugprade instructions on
http://www.gentoo.org/doc/en/gcc-upgrading.xml

If you think things are still majorly hosed, please get on #gentoo-powerpc and
get in my face. I don't want to see these class of errors and want to get to
the bottom of it.

------- Comment #9 From Tom Gall 2009-07-05 20:10:46 0000 ------- 
sticking a fork in it...  I don't like the resolution anymore than you do, I'd
like to see a root cause.
